In one embodiment, a line connecting axes of the rotating discs 11 is an isosceles triangle, and preferably, a line connecting axes of the rotating discs 11 is an isosceles right triangle.
Referring to fig. 2, the turntable 11 includes a rotating shaft 111, a chassis 112, an inner cylinder 113 and an outer cylinder 114. The chassis 112 is circular, and the rotating shaft 111 is disposed at the center of the chassis 112. The axial direction of the rotating shaft 111 is perpendicular to the plane of the chassis 112. The inner cylinder 113 and the outer cylinder 114 are coaxially disposed on the chassis 112 with the rotating shaft 111 as an axis, and both are substantially cylindrical. A bearing space for enclosing the submarine cable 90 is formed between the outer peripheral wall of the inner cylinder 113 and the inner peripheral wall of the outer cylinder 114. The diameter of the inner cylinder 113 is not less than 20 times of the outer diameter of the submarine cable 90 to be laid, so that the operation stability of the rotary table 11 and the submarine cable bearing capacity are improved.

The rotation shaft 111 can drive the chassis 112 to rotate, so as to drive the inner cylinder 113 and the outer cylinder 114 to rotate simultaneously, and further drive the turntable 11 to rotate in a clockwise or counterclockwise direction. In one embodiment, the turntable 11 is a motor-driven electric turntable.
The turntable 11 further comprises a limiting bracket 116, the limiting bracket 116 is mounted at one end of the rotating shaft 111 far away from the base plate 112, the length direction of the limiting bracket 116 is parallel to the plane of the base plate 112, and the limiting bracket 116 can be adjusted at any angle and then locked to control the direction of the submarine cable 90 entering or extending out of the turntable 11. Specifically, the limiting bracket 116 is rotatably mounted at the end of the rotating shaft 111, a limiting groove (not shown) is formed in the limiting bracket 116 along the length direction, and the submarine cable 90 enters or extends out of the bearing space of the turntable 11 through the wire limiting groove along the length direction of the limiting bracket 116.
In one embodiment, the wheel frame 20 is installed at one side of the turntable assembly 10, the turntable assembly 10 includes 3 turntables 11, a connecting line of axes of the turntables 11 is triangular, and a connecting line of axes of the two turntables 11 close to the wheel frame 20 is perpendicular to a cable conveying direction of the wheel frame 20. When three turntables 11 convey the submarine cables 90 at the same time, the angle of the two adjacent submarine cables 90 entering the guide wheel frame 20 is equal by adjusting the limiting brackets 116, and the preferred angle is 45 °. Specifically, with an extension line of the cable transmission direction of the wheel frame 20 as a normal line, the limiting brackets 116 of the rotary tables 11 far away from the wheel frame 20 point to be on the same straight line with the normal line, and an included angle between the extension lines of the limiting brackets 116 of the two rotary tables 11 close to the wheel frame 20 and the normal line is 45 °.
When only two submarine cables 90 are conveyed to the submarine cable 90 at the same time, two turntables 11 close to the guide wheel frame 20 are selected, and the angle of the submarine cable 90 entering the guide wheel frame 20 is equal by adjusting the limiting bracket 116, and the preferred angle is 60 degrees. Specifically, an extension line of the cable transmission direction of the wheel frame 20 is taken as a normal line, and an included angle between the extension line pointed by the limiting brackets 116 of the two rotating discs 11 close to the wheel frame 20 and the normal line is 60 °.

Referring to fig. 4 and 5, the guide wheel frame 20 includes a base 21, a supporting guide wheel 22, and a limiting guide wheel 23. The base 21 is installed at one side of the turntable assembly 10, and the base 21 is a triangular bracket structure to increase the bearing capacity of the guide wheel frame 20. Specifically, the surface of the base 21 contacting with the ship body is a horizontal plane. The base 21 has an inclined surface 211 on the other side to facilitate the transfer of the sea cable 90 from the turret assembly 10 to the strapping machine 30 when the turret assembly 10 is not at the same height as the strapping machine 30. It can be understood that the inclined surface 211 of the base 21 can be adjusted to be horizontal according to the layout of the ship body and the actual situation.
The supporting guide wheels 22 are installed on the inclined surface 211 in parallel along the inclined direction of the inclined surface 211. The support rollers 22 include a plurality of first support rollers 221 and second support rollers 222 spaced between the first support rollers 221. The conveying surface formed by the second supporting rollers 222 and the conveying surface formed by the first supporting rollers 221 are parallel to the inclined surface 211, and the distance between the conveying surface of the second supporting rollers 222 and the inclined surface 211 is greater than the distance between the conveying surface of the first supporting rollers 221 and the inclined surface 211, so as to define the position of each of the sea cables 90 when conveying the plurality of sea cables 90. In one embodiment, the spacing between adjacent first support rollers 221 is 0.5m, and the spacing between adjacent second support rollers 222 is 0.5m, so as to reduce the pressure when the sea cable 90 passes through the support rollers 22.
The limit guide wheels 23 are installed on both sides of the base 21 to prevent the submarine cable 90 from deviating out of the guide wheel frame 20. The distance between the opposite limit pulleys 23 is gradually reduced along the conveying direction to gradually tighten the distance between the submarine cables 90. In one embodiment, the limit guide wheels 23 are movably mounted on two sides of the base 21 through guide rails 231, so as to adjust the distance between the oppositely-arranged limit guide wheels 23, thereby meeting the limit requirements of different numbers and sizes of the sea cables 90.
The number of the guide wheel frames 20 is different according to the number of the submarine cables 90 laid synchronously when in use. When two submarine cables 90 are laid synchronously, the submarine cables 90 enter the sheave bracket 20 through the first support sheave 221. And meanwhile, the distance between the limiting guide wheels 23 is adjusted to be gradually reduced along the conveying direction so as to gradually tighten the distance between the submarine cables 90, so that the two submarine cables 90 tightly cling to the binding machine 30 through the limiting guide wheels 23 at the tail ends, and the parallel binding of the two submarine cables 90 is completed.
When three submarine cables 90 are laid synchronously, the submarine cables 90 on two rotary tables 11 close to the guide wheel frame 20 enter the guide wheel frame 20 through a first supporting guide wheel 221, and the submarine cables 90 on the rotary tables 11 far away from the guide wheel frame 20 enter the guide wheel frame 20 through a second supporting guide wheel 222. And meanwhile, the distance between the limit guide wheels 23 is adjusted to be gradually reduced along the conveying direction so as to gradually tighten the distance between the submarine cables 90. The spacing guide wheel 23 at the end of the conveying is adjusted to have a distance approximately equal to twice the outer diameter of the submarine cable 90, so that the two submarine cables 90 on the first support guide wheel 221 are tightly attached to the spacing guide wheel 23 at the end. Meanwhile, the sea cable 90 on the second supporting guide wheel 222 falls on the two sea cables 90 on the first supporting guide wheel 221 and enters the binding machine 30, so that the three sea cables 90 are bound in a 'pin' -shaped arrangement, and the 'pin' -shaped arrangement effectively improves the structural stability of the bound sea cables 90.
The strapping machine 30 is used to strap the sea cable 90 after being tightened by the wheel frame 20. The strapping machine 30 performs a clockwise rotation of the strapping with a strapping or rope around the tightened sea cable 90 at a speed, the ratio of the strapping pitch to the diameter of the sea cable 90 being between 5 and 8, and the lashed sea cable 90 is then fed into the tractor 40. The strapping tape or the strapping rope is made of seawater corrosion resistant belt materials or metal wires and the like with the tensile strength meeting the requirements.
The hauling machine 40 is used for hauling the bundled submarine cable 90 to the laying assembly 50. The power and size of the tractor 40 meet the requirements of the bundled submarine cable 90. In one embodiment, the tractor 40 employs a track type of traction.
Referring to fig. 6 and 7, the laying assembly 50 includes a rotary base 51, a rotary bracket 52 and a swing bracket 53. The rotating seat 51 is mounted on the hull, the rotating bracket 52 is mounted at one end of the rotating seat 51, and the rotating seat 51 drives the rotating bracket 52 to rotate so as to adjust the horizontal laying direction of the laying assembly 50. The swing bracket 53 is mounted at one end of the rotating bracket 52, and a hydraulic press 54 is arranged at the joint of the rotating bracket 52 and the swing bracket 53 to support the swing bracket 53 and adjust the vertical laying angle of the laying assembly 50. The rotating bracket 52 and the swinging bracket 53 are equally distributed with a horizontal supporting guide wheel and a vertical limiting guide wheel for conveying the bundled submarine cable 90. It will be appreciated that guide wheels supporting the sea cable 90 may be provided on the conveying path of the sea cable 90.
Referring to fig. 8, the present invention further provides a method for applying the submarine cable synchronous laying apparatus 100, including the following steps:
s1, fixing the ends of the submarine cables 90 on the turntable 11 by using traction heads, enabling the traction ropes to pass through the guide wheel frame 20, the binding machine 30, the traction machine 40 and the laying assembly 50 in sequence, and laying the submarine cables 90 on a preset route to be delivered to a landing point or a connection point;

S2, adjusting the limit brackets 116 to make the angles of the two adjacent sea cables 90 entering the guide wheel frame 20 equal;
specifically, in one embodiment, the angle of the two adjacent sea cables 90 entering the guide frame 20 is 45 °. Taking an extension line of the cable transmission direction of the guide wheel frame 20 as a normal line, the pointing directions of the limiting brackets 116 of the rotary tables 11 far away from the guide wheel frame 20 are on the same straight line with the normal line, and the included angle between the pointing extension lines of the limiting brackets 116 of the two rotary tables 11 close to the guide wheel frame 20 and the normal line is 45 degrees.
S3, starting the turntable to enable the turntable 11 to synchronously rotate at the same angular speed, starting traction at the same time, and pulling the submarine cable 90 outwards from the turntable 11 through a traction rope;
s4, under the action of traction force, the submarine cables 90 on the two turntables 11 close to the guide frame 20 enter the guide frame 20 through the first supporting guide wheel 221, the submarine cables 90 on the turntables 11 far from the guide frame 20 enter the guide frame 20 through the second supporting guide wheel 222, and the distance between the limiting guide wheels 23 is adjusted to be gradually reduced along the conveying direction, so that the two submarine cables 90 on the first supporting guide wheel 221 closely pass through the limiting guide wheel 23 at the tail end, and the submarine cables 90 on the second supporting guide wheel 222 fall on the two submarine cables 90 on the first supporting guide wheel 221, and the three submarine cables 90 are arranged in a "pin" shape and enter the binding machine 30;
in one embodiment, the spacing guide wheels 23 at the end of the conveyor are adjusted to have a spacing approximately equal to twice the outer diameter of the sea cable 90.
S5, the binding machine 30 rotationally binds the three sea cables 90 by the binding tape, and the three sea cables 90 that have been bound enter the traction machine 40;
in one embodiment, the rotation direction is clockwise along the cable feeding direction. The strapping may be replaced with a strapping cord. The ratio of the bundled pitch to the diameter of the three sea cables 90 is between 5 and 8.
S6, the hauling machine 40 sends the bundled three submarine cables 90 to the laying assembly 50, and the three submarine cables 90 are laid synchronously.
Specifically, in one embodiment, the three bundled sea cables 90 enter from the side of the rotating bracket 52, and the rotating bracket 52 and the swinging bracket 53 are adjusted according to the sea cable laying line and the water inlet angle to complete the synchronous laying of the three sea cables 90.
Referring to fig. 9 and 10 together, in another embodiment, the turret assembly 10, the wheel frame 20, the binder 30, the tractor 40, and the laying assembly 50 cannot be sequentially disposed on the same plane due to insufficient area of the construction vessel. The wheel carriage 20 may be replaced by a vertical stranding assembly 60, and the turret assembly 10, stranding assembly 60, strapper 30 and tractor 40 are mounted on the ship's level in a vertical direction to reduce the footprint of the synchronous submarine cable laying apparatus 100.
The twisting assembly 60 includes a second rotating shaft 61, a bearing plate 62, a supporting frame 63 and a twisting mold 64. The carrying tray 62 is substantially circular, and the carrying tray 62 is rotatably mounted on the second rotating shaft 61 with the second rotating shaft 61 as an axis. The plurality of rotating discs 11 are uniformly distributed along the circumferential direction of the bearing disc 62, and revolve along the axis of the second rotating shaft 61 under the rotation of the bearing disc 62. In one embodiment, the number of the rotating discs 11 is three.
The support frame 63 is mounted on the second rotating shaft 61, the hinge die 64 is mounted on an end portion of the second rotating shaft 61, and a hinge center of the hinge die 64 is coaxially disposed with the second rotating shaft 61. The supporting frame 63 pulls the sea cable 90 of the turntable 11 to the stranding die 64 for stranding. The stranded sea cable 90 is bundled by the bundler 30, and then the tractor 40 pulls the bundled sea cable 90 to the laying assembly 50 through a steering wheel, and the laying assembly 50 is used for laying the sea cable 90.
During laying, the bearing disc 62 drives the three turntables 11 to rotate counterclockwise around the twisting center at an angular velocity ω 1, and simultaneously the turntables 11 rotate clockwise at an angular velocity ω 2, and ω 1 is ω 2, so that the self axial torsion of the submarine cable 90 when rotating disappears. It is understood that the number of the turntables 11 is adjusted according to the number of the submarine cables 90, and the rotation direction of the turntables 11 rotates clockwise or counterclockwise around the twisting center.
According to the synchronous submarine cable laying device 100 and the synchronous submarine cable laying method, two submarine cables 90 can be laid side by side and three submarine cables 90 can be laid in a shape like a Chinese character 'pin' through the turntable assembly 10 and the guide wheel frame 20, and compared with the conventional mode that a plurality of submarine cables 90 are laid one by one, a large amount of laying time and laying cost are saved for submarine cable engineering construction.
